An excellent point. I don't want to see the Phillies moving on from Bohm. I read columnists saying the Phillies believe perhaps another team will have to be the one to unlock Bohm's full potential. But, his performance this past season was fine: almost 100 RBIs and 3 WAR, and he's still not expensive.
To me, the big point is this: the Phillies have done an absolutely crap job of developing home-grown players who can boost the team. Among the teams they are contending with, they are, perhaps, uniquely awful. We have become a team that tries to succeed by signing or trading for older, expensive players on too long contracts. That is not sustainable.
Now, the Phillies, the same team which allowed Castellanos to play every game, is dissatisfied with the home-grown Bohm after a season in which his performance improved a ton. Meanwhile, Stott and Rojas regressed. We have to go back to Utley to find a home-grown player who has done as well as Bohm. The Phillies are on the same downward path as they were after 2008 and following the same approach in trusting in old, expensive players.
Miller may be our next plus 3B. He might be better than Bohm. Or he might crash and burn as Kingery did. The Phillies seem to have far more than their fair share of that.
An MLB team instills a team culture through home-grown players they have nurtured for years and inculcated their team's approach. We have been this route of only trusting the old guys before. Just as in the 2009-2011 seasons after the WC, the Phillies have left the playoffs earlier each year and have doubled down on established vets.
